[0002] The automotive ignition coil is a core component of the ignition system on a car engine. It enables the spark plug to generate a spark with sufficient energy, thereby achieving the ignition function. An integrated automotive ignition coil combines multiple automotive ignition coils into one housing, allowing multiple ignition coils to be activated simultaneously.

[0003] In existing technologies, ignition elements generally need to be installed inside the housing using fasteners. Operators need to use tools to tighten the fasteners one by one to install the ignition element, which makes the installation of the ignition element quite troublesome.

[0004] This invention proposes an integrated pen-type ignition coil to solve the problem that the ignition element generally needs to be installed inside the housing using fasteners, and the operator needs to use tools to tighten the fasteners one by one to achieve the installation of the ignition element, which is quite troublesome. Summary of the Invention

[0005] The purpose of this invention is to overcome the problem that in the above-mentioned background technology, the ignition body generally needs to be installed inside the housing using fasteners, and the operator needs to use tools to tighten the fasteners one by one in order to achieve the installation of the ignition body, which makes the installation of the ignition body quite troublesome.

[0006] Based on the above technical concept, the technical solution adopted by this utility model is as follows: An integrated pen-type ignition coil includes a main shell, with several ignition elements movably inserted into the bottom of the main shell. A clamping plate is movably fitted onto the outer wall of each ignition element. The clamping plate is connected to the main shell by locking bolts. Several positioning mechanisms are provided on the outer wall of the main shell. The upper end of the clamping plate abuts against the end of the positioning mechanism, and the other end of the positioning mechanism passes through the main shell and abuts against the outer wall of the ignition element.

[0007] Further defining the above technical solution, the bottom surface of the main body shell is fixedly connected with a number of sealing sleeves corresponding to the ignition body, and the ignition body is movably inserted into the sealing sleeves.

[0008] To further define the above technical solution, a sealing ring is fixedly fitted on the outer wall of the ignition body, and a sealing groove is recessed on the top surface of the sealing ring.

[0009] Further defining the above technical solution, a sealing ring is fixedly connected to the bottom surface of the sealing sleeve, the sealing ring is movably inserted into the sealing groove, and an installation groove for installing a positioning mechanism is provided on the outer wall of the sealing sleeve, the positioning mechanism being disposed in the installation groove.

[0010] Further defining the above technical solution, the clamping plate has a through hole for the ignition body to pass through, and the diameter of the through hole is smaller than the diameter of the sealing ring, and the top surface of the clamping plate abuts against the bottom surface of the sealing ring.

[0011] Further defining the above technical solution, the upper end of the locking bolt is movably inserted into the main body shell, and the lower end of the locking bolt passes through the clamping plate and is threaded with a nut.

[0012] Further defining the above technical solution, a plurality of abutment plates are fixedly connected to the clamping plate, and the edges at the upper end of the abutment plates are rounded.

[0013] Further defining the above technical solution, the positioning mechanism includes a positioning rod and a spring. The positioning rod is movably inserted into the mounting groove and connected to the inner wall of the mounting groove by a sleeved spring. One end of the positioning rod extends out of the mounting groove and abuts against the side wall of the contact plate, while the other end of the positioning rod passes through the mounting groove and abuts against the outer wall of the ignition body.

[0014] Compared with the prior art, the beneficial effects of this utility model are: By pulling the clamping plate up and down with the locking bolts, the ignition body is clamped and fixed inside the main body shell. As the clamping plate moves, it comes into contact with the positioning mechanism, which in turn causes the positioning mechanism to move and come into contact with the ignition body, thereby increasing the stability of the connection between the ignition body and the main body shell. Therefore, the ignition body is easier to install.

[0015] The sealing ring and sealing groove work together to increase the sealing performance between the sealing ring and the sealing sleeve. As the clamping plate pushes the ignition body to move, the sealing ring and the sealing sleeve come into contact, which further increases the sealing performance between the ignition body and the main body shell.

[0019] The following is in conjunction with the appendix Figures 1-3 The present invention will be described in further detail below.

[0020] Please refer to the attached diagram in the instruction manual. Figure 1 , Figure 2 and Figure 3 The present invention provides an embodiment of a pen-type ignition coil, comprising a main body shell 1, a plurality of ignition bodies 2 movably inserted into the bottom of the main body shell 1, and a number of sealing sleeves 11 corresponding to the number of ignition bodies 2 fixedly connected to the bottom surface of the main body shell 1. The ignition bodies 2 are movably inserted into the sealing sleeves 11, and the sealing sleeves 11 facilitate the increase of the sealing between the ignition bodies 2 and the main body shell 1.

[0021] The outer wall of the ignition body 2 is movably fitted with a clamping plate 3, and the outer wall of the ignition body 2 is fixedly fitted with a sealing ring 21. The top surface of the sealing ring 21 is recessed and has a sealing groove 22. When the clamping plate 3 pushes the ignition body 2 to move, it causes the sealing ring 21 to abut against the sealing sleeve 11, so as to increase the sealing performance of the connection between the ignition body 2 and the main body shell 1.

[0022] The clamping plate 3 has a through hole 31 for the ignition body 2 to pass through, and the diameter of the through hole 31 is smaller than the diameter of the sealing ring 21. The top surface of the clamping plate 3 abuts against the bottom surface of the sealing ring 21. The through hole 31 allows the clamping plate 3 to be fitted onto the ignition body 2, and as the clamping plate 3 moves, it pushes the sealing ring 21 to move and tightly abut against the sealing sleeve 11, thereby increasing the sealing performance of the connection between the sealing ring 21 and the sealing sleeve 11.

[0023] The clamping plate 3 is connected to the main body shell 1 by a locking bolt 4. The upper end of the locking bolt 4 is movably inserted into the main body shell 1, and the lower end of the locking bolt 4 passes through the clamping plate 3 and is threaded with a nut. The locking bolt 4 and the nut cooperate to facilitate the connection between the clamping plate 3 and the main body shell 1. At the same time, the clamping plate 3 clamps and fixes the ignition body 2 to increase the stability of the connection between the ignition body 2 and the main body shell 1.

[0024] The outer wall of the main body shell 1 is provided with several positioning mechanisms 5. The upper end of the clamping plate 3 abuts against the end of the positioning mechanism 5. The other end of the positioning mechanism 5 passes through the main body shell 1 and abuts against the outer wall of the ignition body 2. A sealing ring 12 is fixedly connected to the bottom surface of the sealing sleeve 11. The sealing ring 12 is movably inserted into the sealing groove 22. The outer wall of the sealing sleeve 11 is provided with an installation groove 13 for installing the positioning mechanism 5. The positioning mechanism 5 is set in the installation groove 13. The sealing ring 12 cooperates with the sealing groove 22 to increase the sealing performance between the sealing ring 21 and the sealing sleeve 11. The installation groove 13 facilitates the installation of the positioning mechanism 5.

[0025] Several abutment plates 32 are fixedly connected to the clamping plate 3. The edges of the abutment plates 32 are rounded. When the clamping plate 3 moves, it drives the abutment plates 32 to move synchronously. Then, the movement of the positioning mechanism 5 can be easily controlled through the abutment plates 32.

[0026] The positioning mechanism 5 includes a positioning rod 51 and a spring 52. The positioning rod 51 is movably inserted into the mounting groove 13 and connected to the inner wall of the mounting groove 13 by the spring 52. One end of the positioning rod 51 extends out of the mounting groove 13 and abuts against the side wall of the contact plate 32. The other end of the positioning rod 51 passes through the mounting groove 13 and abuts against the outer wall of the ignition body 2. The spring 52 facilitates the movement of the positioning rod 51 and its extension out of the mounting groove 13. When the clamping plate 3 moves, it causes the contact plate 32 to abut against the positioning rod 51, thereby causing the positioning rod 51 to abut against the ignition body 2, so as to fix the ignition body 2 in the sealing sleeve 11. When the contact plate 32 separates from the positioning rod 51, the spring 52 pushes the positioning rod 51 to move and separate from the ignition body 2, so as to cause the ignition body 2 to lose its limit, thereby facilitating the operator to disassemble the ignition body 2.

[0027] Working principle: When using this integrated pen-type ignition coil, first install the ignition body 2 inside the main body shell 1, then put the clamping plate 3 on the ignition body 2, and then pull the clamping plate 3 up and down by the locking bolt 4 to clamp and fix the ignition body 2 inside the main body shell 1. As the clamping plate 3 moves, it abuts against the positioning mechanism 5, so that the positioning mechanism 5 moves and abuts against the ignition body 2, thereby increasing the stability of the connection between the ignition body 2 and the main body shell 1. Therefore, the ignition body 2 is more stable when installed.

[0028] The above description is a further detailed explanation of the present invention in conjunction with specific preferred embodiments, which is intended to enable those skilled in the art to understand and apply the present invention. However, it should not be assumed that the specific implementation of the present invention is limited to these descriptions.
